APPLICATION INFORMATION
Power Dissipation Across Device
The power dissipation in the package must be kept below 640mW. Quiescent power is 399mW. Therefore,
power dissipation due to the laser currents must be kept below 240mW.
Connecting to the Input of S3049
The equivalent input circuit of S3049 is shown in Figure 12. Both DC biasing and 50 ohm line termination have
been implemented internally.
